Advanced Timeseries Analytics and Anomaly detection in Fabric Realtime Intelligence
As businesses move toward hyper-responsive operations, the ability to detect anomalies and act on time series data in real time is becoming mission-critical. This session dives deep into how Microsoft Fabric’s Real-Time Intelligence (RTI) stack—powered by Kusto Query Language (KQL)—enables streaming time series analytics and intelligent anomaly detection at scale.
You’ll explore advanced KQL capabilities to:
Build and analyze dynamic time series models over streaming data using make-series, summarize, and render timechart
Apply native anomaly detection algorithms (series_decompose_anomalies, series_outliers, etc.) in real-time
Detect trend shifts, spikes, volatility, and data absence (heartbeat failure) in high-cardinality signals
Combine stateful pattern detection in KQL with event routing via Activator for intelligent automation
We’ll walk through real-world use cases—like monitoring IoT telemetry, infrastructure stability, and SLA breaches—and showcase how to embed anomaly detection directly into streaming dataflows with sub-minute latency using Eventstreams, KQL, and Activator.
Expect hands-on demos, deep syntax insights, and performance tuning tips for advanced users. Whether you're building operational alerting for manufacturing or real-time analytics for finance, this session will help you take full control of your time series data in Fabric.
KQL Kickstart: Dein Einstieg in die Kusto-Abfragesprache
Nie zuvor wurden so viele Daten erzeugt und gesammelt wie heute. Diese Daten türmen sich auf zu einer unendlich großen Datenmenge die irgendwie verarbeitet und abgefragt werden muss. Eine Möglichkeit gigantische Datenmengen zu verarbeiten stellen die KQL-Datenbanken dar, die Bestandteil von Azure Data Explorer, Log Analytics oder Fabric Realtime Intelligence sind. In dieser einführenden Session erklärt Data Platform MVP Frank Geisler die Grundlagen von KQL, der Kusto Query Language, Sie werden lernen wie die Sprache aufgebaut ist, welche Operatoren es in KQL gibt und wie man einfache Abfragen schreibt. Nachdem wir die Grundlagen behandelt haben, werden wir uns mit weitergehenden Themen wie Zeitreihenanalyse, Visualisierung von Datensätzen (ja, auch das geht in KQL) und den Möglichkeiten von Graph Datenbanken in KQL beschäftigen.
The complete guide to certifications for a Microsoft Fabric professional
In this session we guide you through preparing for the DP-600 & DP-700 certification exams. Join two Data Platform MVPs as they use their real-world experience in the Data Engineering arena to help you prepare, practice, test and become certified.
Topics we cover during the workshop offer a holistic overview of what is required to pass Microsoft Fabric Certification exams and includes:
• Breakdown of the latest skills measured for the exam.
• Guide through each of the workloads covered for the exam.
• Targeted focus of the skills measured in each workload.
• Demonstrations on how to self-prepare for the exam.
• Expert exam tips.
• Recommended resources.
During the workshop we will also show demos to see where some elements are connected to help with memory muscle. For example, a real-time demo to show how various items in the lifecycle management are connected and an end-to-end Real-Time analytics demo from an industry recognized expert.
At the end of this workshop, you will have a good overview about what is required for you to pass DP-600 and earn your Fabric Analytics Engineer Associate certification or the DP-700 for Implementing Data Engineering Solutions Using Microsoft Fabric.
Build A Fabric Real-time Intelligence Solution in One Day
Real-Time Intelligence in Fabric is designed to enable organisations to bring their streaming, high-granularity, time-sensitive event data into Fabric and build various analytical, visual and action oriented data applications and experiences with it. In this session, you will learn about what Fabric Real-time Intelligence is meant for and will then build an end-to-end solution using streaming data.
This session will get you hands-on with Real-Time Hub, Eventstream, Eventhouse, Data Activator, Real-time Dashboards, Power BI, and Copilot with combination of Microsoft MVPs and Fabric product group members to guide you along the way.
The end-to-end solution we build together will encompass:
• Discovering and cataloging your data streams using Real-Time Hub
• Connecting to streaming data from various sources around the world
• Cleaning, normalizing, preparing data for superior query time experiences
• Leveraging Copilot to discover streaming data
• Low-code/no-code experiences for data exploration
• Developing dashboards
IaC Thunderdome: Bicep vs. Terraform!
As organizations increasingly adopt cloud technologies, managing infrastructure efficiently becomes paramount. Infrastructure as Code (IaC) tools play a crucial role in achieving this goal. In this session, we delve into a head-to-head comparison between two popular IaC tools: Bicep and Terraform. Specifically, we explore their strengths, weaknesses, and suitability for data infrastructure scenarios.
During the session we will dive into the following aspects:
1. Language: When you have understood the concept of Infrastructure-as-Code both Bicep and Terraform code is quite readable. Bicep is a relatively new language while Terraform is more mature and have a rich ecosystem. How are they licensed and how will that affect you in your scenario?
2. State and Backend: How do Bicep and Terraform handle state management? What are the implications of incremental deployment in Bicep and how do Terraforms required use of a state file affect scalability? How is configuration drift handled in the two tools? How do you make sure to secure your IaC backend from bad actors
3. Infrastructure Targets: Bicep is Azure exclusive while Terraform has multi-cloud support. Besides the obvious, how does that affect you, if at all?
4. CLI Tools: We do a comparison between Bicep’s integration with Azure CLI and Terraforms CLI. Furthermore we show practical examples of using CLI commands for deployment.
5. CI/CD: How can you streamline your IaC delivery with tools like Bicep and Terraform, especially when you have multiple team members contributing to your cloud? How is testing handled and do regression-testing of IaC exist? We’ll have a look at possibilities using GitHub for this.
The session concludes with decision factors for Bicep or Terraform, so when should you use what taking factors like cloud environment, project scope and team expertise into account. We will give you some best practices for making an informed decision. Join us for an insightful session where we dissect Bicep and Terraform, equipping you with the knowledge to make informed choices for your data infrastructure projects.
PowerShell and dbatools - Your secret Superpower
Being a Database Administrator is a daunting task. So many things to do, so many tasks to fullfil. Why not getting in your phone booth, change your cloths and be the superhero everyone is waiting for? In this demo packed session german Data Platform MVP Frank Geisler will give you an introduction to automate everyday SQL Server tasks though PowerShell and dbatools. After that everyone will ask..."Is it a bird?", "Is it a plane`?" "No it is a PowerShell and dbatools guru"...
Automating Power BI with PowerShell
In this Demo packed Session German Data Platform MVP Frank Geisler will show how to automate Power BI adminitstrative task with Power BI. Attendees will learn where to get the tools, what can be automated. There are several easy to follow examples, e.g. how to automatically create a Power BI Dataset via PowerShell or how to build a Power BI Inventory.
Data Wranglng the PowerShell way
Data is the Oil of the 21th century as The Economist once titled. In a perfect world this data is stored in the perfect data model, either on prem or in the cloud, nicely formed and ready to use. Right? But we live in a world that is far away from this. Data is everywhere. It is in SharPoint Lists, CSV Files, Excel Files, maybe in your System, maybe in another Application, even in your Active Directory. Often there are requirements to transform this data from one Data Storage to another just to sync data between different sources or just because the boss wants some Excel file (sigh). A big Data Transformation Solution like SSIS or Azure Data Factory might not always be the best solution to accomplish these tasks. Join german Data Platform MVP Frank Geisler in a demo centric session where he demonstrates how to transform data between different data sources with PowerShel, dbatools and ImprortExcel and do all this little transformations in the blink of an eye. And remember your Boss waiting on his Excel Sheet? Even this can be archeived easily through PowerShell!
